FLUID-PRESSURE MOTORl FOR DRIVING TORPEDOES.

To aZZ whom it may concern Be it known that I, GEORGES HENRI MARIUsCANTON, citizen of the Republic of France, residing at 9 Avenue desMoulineaux, Billancourt, Seine, in the Republic of France, have inventednew and useful Improvements in Fluid-Pressure Motors for DrivingTorpedoes, of which the :following is a specification.

This invention relates to improvements in fluid pressure motors fordriving torpedoes.

It is known that motor driven torpedoes actually used in the navies ofdifferent countries are driven at a speed which is but little greaterthan the maximum speed of the most' rapid war ships. Under theseconditions the chances of success in an attack are slight. This lack ofspeed in torpedoes is due to the fact that hitherto a motor capable ofproducing suiiiciently high power in a size sulficiently small to behousedin the torpedo has not been produced.

The present invention has for its object a motor intended especially fortorpedoes and driven by the same motive Huid usually em- -ployed intorpedo motors, that is to say compressed air. l

The improved motor comprises several cylinders parallel to the motorshaft each of which cylinders contains two oppositely working pistons,connected by rods and universal joints to inclined oscillatory platesvmounted on the motor shaft and coperating with inclined rotary platesfixed on the said shaft. The distribution of the, compressed air iseffected by piston valves and the inlet and the exhaust of the motivefluid is operated by annular collectors.

The annexed drawing illustrates an example of construction of theinvention.

Figure 1 is a longitudinal section of the motor. Fig. 2 is a transversehalf section. Fig. 3 is a partial section on line A-A, Fig. 2. Figs. 4and 5 are respectively partial sections on lines B-B and C-C of Fig. 3;Fig, 6 is a diagrammatic view in vertical section, of the torpedoprovided with the improved motor.

The motor represented comprises a frame or casing provided with two caps1 in which a shaft 2 rotates on ball bearings. This shaft actuates thepropeller` or propellers of the torpedo, for instance by means of theknown device shown in Fig. 6. The caps carry interiorly plates 1abetween which six Specification of Letters Patent. VPamiqgned Aug; 31,1&15.

cylinders 3 are mounted in each of which two pistons 4 work. Each ofthese pistons is connected by a rod 5 and av joint 6 to an oscillatingplate 7 made in two pieces and common to all the pistons 4 situated onthe same side of the motor. This oscillating plate is arranged obliquelywith regard to thel motor shaft 2 which traverses it. One of itsdiameters is obliged to 'remain constantly in the same plane passingthrough the axis of the motor shaft. Each plate 7 is provided with aconical toothed crown 8 the teeth of which engage in those of acorresponding fixed toothed crown 9. The two crowns 9 as well as ballbearings 9a carrying thel motor shaft, are supported by plates la.

VThe oscillating plates 7 transmit the movev160 kgr. It is first reducedto a pressure of about 20 kgr. by an expander 16 and is then reheated toabout 300O C. in a reheater 17. It passes then into a collector formedby an annular conduit 18 and serving for the admission. From thisconduit, branch pipes 19 lead which feed the distribution boxes 2Osituated one on the side of each cylinder. These boxes communicate withthe corresponding cylinder 'by a port 21 (Figs. 3 and 4). They areconnected also, by branches 22 to a collector 23 formed by an `annularconduit analogous to the conduit 18 and serving for the exhaust.

In each distribution box 2O is a piston valve 24 slidable therein andwhich is also guided in a sleeve 2Oa xed inside the box. According tothe position of this piston valve,.the working chamber between the twomotor pistons 4 of the corresponding cylinder, is put in communicationwith the admission orwith the exhaust or is completely cut off therefromas shown in Fig. 3. Each piston valve carries a rod 25 which is governedby a lever 26 (Fig. 2) pivoted on the cylinder and carrying, at itsother end a roller 27 which rolls in a cam groove 28 formed in a sleeve29 fixed to the motor` shaft. This groove or cam is cut so as tosuccessivelyactuate the various piston valves in order toproduce thevarious phases of the cycle in each cylinder.

The invention is naturally not limited to the details of constructionrepresented and described.

Having now described myinvention, what I claim as new and desire tosecure by Letters Patent is:

l. In a compressed air motor for driving torpedoes, the combination of aplurality of cylinders extending parallel to the motor shaft, a pair ofoppositely working pistons in each cylinder, a two-part oscillating'non-rotatable plate connected to each set of pistons, inclinedrotaryplates keyed on the motor shaft and embraced between the parts of saidoscillating plates, and antifriction means between said platesandthrough which power is transmitted from the oscillating plates to therotary plates.

tor shaft and embraced between the parts of said oscillating plates,anti-friction means between said plates and through which power istransmitted from the oscillating plates to the rotary plates, oppositelydisposed iXed conical pinions, anda conical ,pinion carried by each ofsaid oscillating plates, said last named pinions meshing with said fixedpinions. r

In testimony whereof I have signed my 40 name to this speciication inthe presence of two subscribing witnesses.
